Taxpayers fall into one of seven brackets, depending on their taxable income: 10%, 12%, 22%, 24%, 32%, 35% or 37%. Because the U.S. tax system is a progressive one, as income rises, increasingly higher taxes are imposed. But those in the highest bracket don’t pay the highest rate on all their income. For example, for 2019 taxes, single individuals pay 37% only on income above $510,301 (above $612,350 for married filing jointly); the lower tax rates are levied at the income brackets below that amount, as shown in the table.

The table displays tax brackets according to filing status: single, married filing jointly or qualifying widower, head of household and married filing separately. The IRS makes inflation adjustments each year.
